e, 1909. Serial No. saeesaaglssm Application filed December 1 To all whom it may concern: Be itjlrnown that I, JOHN PEARSON, a citizen of the United States, residing at Chica o, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in. Car-Roofs, of which the following is a specification, reference beinghad therein to the accompanying drawmg.

"invention relates to metallic car roofs,

and consists in the peculiar and novel fea-' tures herein described and then pointed out in the appended claims.

In the accompanying drawings, which illustrate practical embodiments of the various features of my invention and in which the same reference numerals indicate similar parts in the different figures, Figure 1 is a top plan view of a portion of a car roof showing certain features of my invention, parts being omitted for the purposes of illustration; Fig. 2 is a sectional view on the line 22 of Fig. l where one of the roof panels is shown in place and with one of the ear:

line-caps and the ridge cover in place; Fig.

3 is a sectional view taken on the line 3--3 of Fig. 1 where the roof panel or sheet is omitted Fig. 4 is a top plan view of a sectionof the roof with the carline-webs and the sides of a pair of panels and of an asso- 'ciated carline-cap in section; Fig. 5 is a perspective vlew of one of the carline-caps with its outer end shown in section; Fig. 6 is an end view of the inner end of the carline-cap in elevation; Fig. 7 is a sectional view of the carline-cap near its outer end; Fig. 8 is a sectional detail view on the line 8-8 of Fig. '10 showing one of the carlines and portions of an assembled panel, a carline-cap, and aridge-cap section; Fig. 9 is atop plan view of a section of the roof at the ridge showing the arrangement of ridge-caps, carlines, and other parts; Fig.10 is a perspective view showing some of the parts of Fig. 9; and Fig. 11 is a sectional view on the line 1111 of Fig. 9.

In the drawings the reference numeral 15 designates the ridge pole, 16 the side-plates, 17 the side sheathing 18 the facia or crownmold, 19 the longitudinal metallic side-bars substal'ltially Z-shape in cross-section, and 2.0 the longitudinal wooden purlins. Extending transversely of the roof at suitable intervals are the metal carlines which in the present invention are in theshape of I- beams having upper and lower flanges 21 and 22 and connecting webs 23, the car-lines extending from side to side of the car and resting upon the ridge pole, purlins, and side plates. The earlines are connected to the-side bars 19 lie brackets-24 which are bolted to the bars and-to the-lower flanges of the carlines as clearly shown in Fig. 3. transversely of the roof are a series of wooden strips 25 which are associated in pairs with the carlines, being cut-away or routed-out along one edge to rest upon the lower flanges 22 thereof as. shown in Fig. 8 and being secured to the side-plates. and purlins by bolts or other suitable connecting' devices as clearly shown in Fig. '3. The car-lines are arranged parallel with each other at suitable intervals, and the roof sheets or panels 26 which extend. from the' ridge-pole outward to the eaves rest upon the wooden strips 25. Each sheet or panel is substantially rectangular in shape but is slightly narrower at its inner end than at its outer end, being slightly tapered inwardly for this purpose as clearly shown in Fig. 4, and is provided with upturned side flanges 27, an up turned inner flange 28, and a down-turned outer flange 29 adapted to extend down upon the outer face of the crown-mold 18 as clearly shown in Fig. 2. By constructing the roof sheets in the inwardly tapered form shown I amenabled to interlock them with the carlines by means of suitable carline-caps in such manner as to securely hold them in place but to permit their inner ends to have a slight play or movement under any undue strains upon the car.

The carline-caps are of metal and each consists of an upper horizontal portion 30 of sufiicient width to overlap the flanges 27 of a pair of panels or plates, down turned sides 31, and outwardly extending flanges 32; at their inner ends adjaccntthe ridge pole the caps are formed in substantially inverted trough-shape as shown in Fig. 6, and from their inner ends the sides are gradually inturned under the horizontal portion 30 as clearly shown in Fig. 5 toward their outer ends where they assume in cross-sectionthe. form shown at the left-hand end of Fig.,5 and in Fig. 7. These parline-caps extend Also extending from the ridge 'pole outwardly to the eaves Where they are provided with down turned outer ends 34: overlying the down turned portlons 29 of the root panels, suitable fastoning 115L118 passing through the down turned portionsB-t and 29 into the crownmold and side-plates as shown in Fig. 3.

After the roof plates are assembled upon their supporting strips 25 on each side of the carlines, one of the carline-caps slipped into place along the length of the associated carline beginning at its outer end and when the cap is in place in the position shown in Fig. 2 its down turned sides enibrace the upper flange of. the carline and the outer portions of the up-turned flanges 27 of the associated panels as shown in Figs. ia'nd 8, leaving the inner portions of these flanges free to move or play under strains or twisting. actions of the car. I also provide a sectional ridge-cover, each section being adapted to interlock withthe adjacent ends of a pair of opposite carline-caps at the ridge or center and extending longitudinally of the car over the up-turnecl inner flanges 28 of an opposite pair of plates and telescopically engaging the neXt section of the r dge-cover.

This cover is made of metallic sections which are substantially in the formofa Roman cross, in whichthe crossarms are shorter than the body;'-as shown in Figs. 9 and 10 the longitudinal portion of each section comprises a body 36 and head 37 each consisting of a trough-shaped structure comprising a top or upper portion, downturned sides 38, and lateral flanges 39 adapted to overlie and rest upon the upper facesof a pair of opposite plates or anels 26 with the upper flanges 28 thereof in the troughs provided by the sides and top. The

cross-slate 40 of each section is raised above a the plane of its body or head and is pro vided with downturned sides 41 andlateral flanges 42, the latter lying in the same plane 'as, and 'beingextensions of, the flanges 39. Each cross-piece fits over and receives the adjacent ends of an opposite pair of carlinecaps as clearly shown in Fig. 10; each head '37 is wider in cross-section than the body so thatthe end of the body fits within thehea'd of the next section by an overlapping or telescoping joint as shown inFig. 9. 'The cross-pieces 40 are oppositely inclined from their centers to fit the pitch of the roof as shown in Fig. 11, as are the flanges 39 and v 42. In assembling the parts one of. the sections of the ridge-cover is placed in posi-' tion upon theadjacent ends of a pair of opposite carline-caps with the portion-40.

overlying the same and holding them in alinement and with the portions 86 and -37 overlying the up-turned flanges 28 of the four associated plates or panels. As the head of each section -is slightly larger than the it fits or't'elescope's over the lower end of the body of the next section as clearly shown in Fig. 9, thereby enabling the sectlons to lap and have slight longitudinal inotion'one upon the other caused by the movement of the .parts of the roof. when under undue strain.

A running-boardsaddle 43 is fitted-over each of the upturned portions l0 of the ridge-cover and the associated carline-caps, and the running boards 44 are properly secured to the saddles, which are bolted .to the upper flanges'2l of the carlines as shown at 45 in Figs. 8 and 1.1. The saddles are suitably routed out or shaped to fit over the ridge-covers and over the carline-caps to rest upon the plates 26. The lower flanges of the carlines are secured to the purlins by bolts 46, the strips 25 being countersunk over the heads of the bolts as shown in Fig. 8.

. Various modifications and changes'in the arrangement and construction of the sev-' eral parts may be made without departing from the'scope of my invention.

I claim:

2. In a car roof, a series of carlines, metal 'panels wider at their outer than. at their inner ends and having upturned sides adjacent the carlines, and caps having tops and sides covering, the carlines and joints between the panels, the sides of the caps being gradually inturned under the top from their inner toward their outer ends.

3. In a carroof, a series of I-shape carlines, metal panels wider at their outer than at their inner ends and having upturned and tapering in width toward the ridge of the car, upturned flanges on the panels adjacent the carline-webs, and carline-caps of inverted trough shape having sides vertical at their inner ends and inturned at their outer ends.
